Oatey 530-11910 Roof Flashing Thermoplastic 3 in

Product Description

The OATEY 530-11910 is a thermoplastic roof flashing designed to create a watertight seal around plumbing vent pipe penetrations through roofing surfaces. Constructed from rigid black thermoplastic, this flashing resists fading and cracking over time, making it a dependable choice for exposed rooftop installations. The no-caulk design slips directly over the vent stack and automatically adjusts to fit the pipe size and roof pitch, reducing installation time and eliminating the need for additional sealant. Licensed plumbers and roofing contractors install this type of flashing during new construction or re-roofing projects.

This flashing is suited for both residential and commercial applications where plumbing vent pipes penetrate a roof deck. Common install scenarios include single-family homes, multi-unit residential buildings, and light commercial structures where a clean, self-adjusting boot is required at the vent stack exit point. The 3-inch size accommodates standard vent stack diameters used in typical DWV (drain, waste, vent) systems.

Installation Notes

Installation is typically performed by a licensed plumber or qualified roofing contractor. Before installation, ensure the roof surface is clean and the vent stack is clear of obstructions. Slide the flashing boot over the vent pipe and position it flat against the roofing material, integrating it with the surrounding roofing underlayment and shingles per local building code requirements. Follow all applicable IPC and local plumbing code guidelines for vent penetration waterproofing.
